Mended at last (6)
I believe the answer is:
heeled
'mended' is the definition.
(heeling is a kind of mending)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for heeled that I've seen before include "Played the part of a hooker" , "Tilted; shod" , "Most shoes are" , "listed" , "As shoe may be repaired" .)
